# Update enterprise ECDSA MPC challenge

`PUT /api/v2/enterprise/{enterpriseId}/tssconfig/ecdsa/challenge`

This api is used to upload a new ECDSA challenge for the enterprise. This will replace the existing challenge if one exists.

## Path parameters

- `enterpriseId` string, required

## Request body

- object
  - `enterprise` UpdateEnterpriseChallenge, required
    - `ntilde` string, required — Range proof challenge value.
    - `h1` string, required — Range proof challenge value.
    - `h2` string, required — Range proof challenge value.
    - `verifiers` object, required
      - `adminSignature` string, required — The admin signature is a hex string. Users should verify that the admin signature matches for the range proof challenge.
    - `paillierBlumProof` PaillierBlumProof — The paillierBlumProof value is only required when creating the initial config.
      - `w` string, required — The w value of the Paillier Blum proof
      - `x` string[], required
      - `z` string[], required
    - `ntildeProof` NtildeProof — The ntildeProof value is only required when creating the initial config.
      - `h1WrtH2` object, required
        - `alpha` string[], required
        - `t` string[], required
      - `h2WrtH1` object, required
        - `alpha` string[], required
        - `t` string[], required
  - `bitgoNitroHsm` UpdateBitgoChallenge, required
    - `verifiers` object, required
      - `adminSignature` string, required — The admin signature is a hex string. Users should verify that the admin signature matches for the range proof challenge.
  - `bitgoInstitutionalHsm` UpdateBitgoChallenge, required
    - `verifiers` object, required
      - `adminSignature` string, required — The admin signature is a hex string. Users should verify that the admin signature matches for the range proof challenge.
